Application Unteren@ resi ding invention aims to provide novel means oicontrolling the dow of the fuel, and to provide novel means for cleaning the device.

it is within the province of he disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

With the above and other objects in view., which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, Wit-hin the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit ofthe invention.

In the accompanying drawings Figure l shows in longitudinal section, a device constructed in accordance with the invention, parts being broken away, and

parts appearing in section; Figure 2 is a side elevation of the hand wheel and attendant parts; Figure 3 is a transverse section on the line 3 3 of Figure 1; Figure 4 is a transverse section on the line 4,-4 of Figure 1. Figure 5 is a cross section taken through the hub of the handY wheel and parts therewithin.

The device forming the subject matter of thisapplication includes a body comprising a tubular member 60. A cup-shaped nozzle v6l is provided, the same being threaded :it

62 on the forward end of the tubular membed 60, the nozzle including an end wald 63 having an outwardly extended seat 6e wherein an outlet 65 is fashioned. A tubular guide 66 is located within the nozzie 6l and is provided at its forward end with an outstanding ange 67 abutting against the end Wall 63 o the nozzie. At its rear end, :the tubular guide 66 is supplied with radial arms 68 extended within the forward end oro the tubular member 60, and having fingers 69 engaging the forward end edge o the member 60. Obviousiy when the noseriel ilo. $9,226.

threaded on the tubular member tiaily te bore of the guide 66, the inner he slits O communicating with interior ci the guide 66, and the outer ends of the slits communicating with the ciiainber which exists in the nozzle 6i, about the guide l The numeral 7l denotes a foot the rear end of the tubular member 60 being threaded into the or being mounted otherwise therein. The foot 71 has a lateral inlet 72.

iii plunger, denoted generally by the numeral 53, is mounted to slide in the body of the burner, the plunger being a composite structure and including a tube or guide 74. 'i

A valve 7 5 is mounted removably in the forward end of the tube 75 and is slidably received in the tubular guide 66, the forward end of the 'valve being so shaped that it will cooperate with the outwardly extended seat 64 in the end wall 63 of the nozzle 6l, and control the paage of fuel through the outlet 65. The plunger 73 embodies a screw 76, wherein the rear end of the tube. or guide' 74 is mounted. The screw 76 is threaded at 89 into the foot 71 and has an external shoulder 90, the screw 76 having a reduced neck 77 including a poly onal art 110. The neck 77 has an interna shou der 78. The numeral 7 9 marks a hand Wheel comprising a tubular hub 80 provided at its inner end with a ange 81, the lange having a polygonal open 111 receiving the part 110 of the neck 77 of the screw 7 6 and abutting against the shoulder 7 8. A nut 82 is threaded/on the rear end of the neck 77 of the screw 7 6 and is located Within the hub 8() of the hand wheel 7.9, the nut bearing against the flange 81, and binding the same against the shoulder 7S the construction being such that when rotation is imparted to the band wheel 79, rotation will be imparted to the screw 76 and to the other parts of the plunger 73 hereinbei'ore alluded to.

On its outer surface, the hub 80 of the hand wheel 79 is provided with a scale 83, constructed as desired. A carrier 84, in the form of a collar is circumferentially adjustable on the rear end of the foot 7l, and.

is held in place, adjustably, by a set screw 'ildti Afashioned in the rear end of the foot 71.

The` carrier 84 embodies a rearwardly extended arm 87, the rear end of which is disposed close to the hub 80 of the hand wheel 79, the arm carrying a Vernier 88 adapted to coact with the scale 83 on the hub 80 of the hand wheel 79.

A stop ring 91 is located in the rear end of the foot 71 and abuts against an internal shoulder 92, formed in the foot 71. A packing 93 surrounds the neck 77 o f the screwL 76 and abuts against the stop ring 91. An I annular pressure member 94 is received slidably within the rear end of the foot 71, the neck 77 of the screw 76 sliding in the pressure member, in the packing 93 and in the 'stop ring 91. `A nut 95 is threaded externally on the rear end of the foot 71, the nut and the pressure member 94 being supplied with cooperating annular anges 96, the construction being such that when the nut 95 is advanced, the. pressure member 94 will be advanced likewise, the packing 93 being compressed about the neck 77 of the screw 76.

In practical operation, rotation may be imparted tc` the plunger 73, by means of the hand wheel 79 and because the screw 76 is threaded at 89 into the foot 71, the plunger 73 may be retracted from the position shown in Figure 1, the forward end of the Valve 75 being spaced from the end wall 63 of the nozzle- 61. Under such circumstances. the fuel will enter through the inlet 72 and will 'traverse the tubular member 60, the fuel paing between the arms 68 of the guide 66, and entering the chamber which exists about the guide and within the nozzle 7l. Proceeding from thence, the fuel traverses the slits or ports 70 in the flan e 67, and enters the tubular glide 66 in a Vance of the retracted valve 75, the fuel deriving a whirling motion,

l from the outlet 65.

Itis obvious that the plunger 73 may be adjusted forwardly or backwardly, to a -ne degree, owing to the fact that the arm 87 is provided with the Vernier 88 coacting with the scale 83 on the hub 80 of the hand wheel. It is possible to loosen the set screw 85, whereupon the carrier 84 and its arm 87 may be shifted circumferentially of the part 7,-

to the end that the Vernier 88 may be so set as to be read without difficulty, due regard belng had to the way in which the device is mountedfi'n a boiler furnace. Referrin to Figure 5, it will be seen that the hand w eel 79 may be adjusted circumferentially on the part 110, the cpnstruction and operation bemg such that the zero of the scale 83 may be at the top and exposed plainly to View, regardless of the position of theoutlet 72.

As thus far described, the device embodies means whereby the flow of fuel may be regulated to a line degree.

It is contemplated, further, that means shall be provided whereand issuing in a flamev rod,-mounted to reciprocate in the tube 74,

the tube acting as a guide for the rod. The rod or main member 98 is. slidable, further in the screw 76 and in the neck 77 thereof. A tip 99, in the form of a pin, is secured removably at 100to the forward endof the rod 98 and is mounted for reciprocation in the Valve 75. A recess 101 is formed in the neck 77 of the screw 76 vand therein a compression spring 102 is located. The forward end of the compression spring 102 abuts against the neck 77 of the screw (6, the rearend of the compression spring engaging an abutment 103, attached by a securing element 104 to the main member or rod 98 and received slidably in the recess 101 of the neck 77. A packing 105 surrounds the rod 98' and is located in a cavity in the nut 82. A screw plug 106 is threaded into the nut 82 and serves as a means for compressing the packing 105 about the rod 98, the rod being mounted slidably in the screw plug. A finger piece 107 is secured at 108 to the outer end of the rod 98 and is adapted te be received in a chamber 109, formed in the hand wheel 79.

it will be obvious that reciprocation may be imparted to the cleaner 97, through the instrumentality of the linger piece 107, the spring 102 being compressed when the cleaner is advanced, and serving to assist in the rearward movement of the cleaner. When the cleaner is reciprocated, the tip 99 of the cleaner moves in and out of the outlet 65, accumulations of carbon or other foreign material being removed from the outlet 65. When the cleaner 97 is retracted, due .to the action of the spring 102, the abutment 103 engages the nut 82, the forward end surface of the tip 99 being located flush with the forward end surface of the valve 75, it thus being impossible for carbon to accumulate in the bore of the valve 75 wherein the tip' 99 operates.
